The Jagged Little Pill star has three children – nine-year-old son Ever, daughter Onyx, three, and seven-month-old son Winter – and admitted she has drawn from her own emotional experiences for new album Such Pretty Forks In The Road.

Morissette, 45, told This Morning: “[The new album] is intense. I like to think I write about all the things in my unconsious - which is liberating.

“There are postpartum chapters in my life from all three of my pregnancies. The first two depression, and the most recent one more anxiety.

“But medication saved the day for me.”

The You Oughta Know singer found global stardom with her 1995 album Jagged Little Pill in which admitted chanelling all her feelings of “anger, fear and sadness”. The best-selling album of angst and frustration resonated with a generation of young people at the time.

Her new single is called Reasons Why I Drink.

She said of singing about very personal subjects: “It’s vulnerable to write it but I’m isolated in the studio so actually it is somewhat cowardly to hide away and write about it. But it’s also really empowering - there is no secrecy.”

Morissette revealed it is harder to find time to write music with her three kids around, but revealed: “I’ve written songs where there is a knock on the door and my son comes in and there is a hand on my shoulder while I’m writing.”
